' Application nea January 16. 190s. sein No. 139.263. (No modem Y To allwhom t may concern: i A

Beit known that I, THOMAS FRANCIS MUR-l PHY, a citizen of the UnitedStates, and' a resident of vNew York, county ofv New York, and State ofNew York, have invented certain new and useful Improvements in AutomaticHydrants,of which the followingis aspecification, reference being had tothe accompanying drawings, forming a part thereof, in which similarcharacters of reference indicate correspending parts.

This invention relates to automatic hydrants, and has for its object toprovide an efficient and improved apparatus of this character which isf`especiallyadapted for use in vpublic placesas parks, the constructionbeing such as to prevent waste of water and readily supply any demand inrequired quantities.

The apparatus embodies principally a suitably-housed Valve which isnormally seated over the source of watersupply `and a drinking vesselarranged in connection `with n the valve and of such relative proportionIn ythe accompanying drawings, I forming part of this specication,Figure 1 is a vertical sectional elevation o f my improvedhydrant; Fig.2, a sectional plan view taken on the line :n of Fig. l, and Fig. 3 'isa vertical sectional elevation illustratinga modification ofconstruction. v

In .the drawings as illustrated by Figs. 1 andv 2, A represents ametallic housing of T'- shaped contour embodying the verticalcylindrical part 1 andv laterally-extended part 2. Threaded into theupper end of the cylinder 1 is a plug B, and the lower end of saidcylinder is threadedto a supply-pipe C, which communicates with thesource of water-supply. A tubular spout D is threaded inr-o the lateralextension 2 for the discharge of water.

Seated on the upper end of the supply-pipe y ,i C' is a valve E, whichembodies the metallic Patented December s, 19oa.

Adisk e and rubber or other flexible disk c', the

latter being held on the disk c by means of the screw e2, whereby it.,may be renewed when worn.

lcentral opening leading through the plug B to allowvertical-movementof'the stem with-V Extended from the disk e isa stemE', which is ground to dt within a verticalZ 4which forms, preferably,an integrall part of the housing A. The outer end of the lever F isprovided with an eye f, which engages one end of a chain-Gr.l This saidchain is inI connection with a drinking vessel H, which embodies thebowl or cup h, handle h', and eye h2, which is secured to the lower endof 'the chain G.

' The above-described drinking vessel H is `composed, preferably, ofmetal, and it is Of v suiiicientweight to overcome by its gravity thepressure from the water-main and keep the valve E seated over the outletof the supply-pipe C when said vessel is in suspended position, asillustrated by full lines, Fig. 1 of toPOstion illustrated by dottedlines, Fig. 1, the'pressure from the main forces the valve E upwardly,causing the washer c4 to rest against the lower end of the plug B toprevent 4leakage and at the same time allowing free outflow of waterthrough the spout D.

Incasing the above-described construction is a hollow standard I,embodying ataper ing upright 7l, the drip-basin t', circular dogtrough012, and base is, suitable anchor-posts '4 being provided 'to keep thestructure in rigid upright position. The top of the standard I ismaintained normally closed by means of the cap I', having the slot i6 toaccommopurpose of repairing the hydrant.

An outlet-opening 115 is extended from the basin t into the upright ilto allow waste water to drip into the dog-trough i2. To prevent overflowof the dog-trough, a discharge or waste pipe .I is extended through thebottom of the dog-trough to a point slightly below the upper levelthereof. The supply-pipe C communicates with an auxiliary pipe C', whichleads from the main to provide a continuous supply of water to thedevice.

As a means of access to the inner part of the trough 2, whereby the samemay be cleaned, a doorway I2 is formed through the standard I andprovided with a normally closed door I3.

To assure instant opening ofthe valve E when the vessel H is lifted, aspring, as f', is located beneath the lever F to lift said lever andallow free upward movement of said valve and its stem; but the nature ofthis spring is such that its tension is readily overcome by the gravityof the vessel H.

In the modification of my invention illustrated by Fig. 3 of thedrawings the hydrant is housed within a bowl K, having an overhanginghood K', and the spoilt embodies the tubular sections 5, 6, and 7, heldtogether by suitable elbows 8. This housing is adapted to be set withina recess of a wall of a building, car, &c., whereby the bowl onlyextends outwardly. In this structure the lever F is provided with anupwardly-extended part f3, which bears against the under part of ahinged screen or drip-plate L, whereby said lever by the action of itsspring f4 will lift the dripplate to allow the valve E to open bypressure from the main when no Weight is on the drip-plate L. The weightin this construction, as in the other previously described, embodies acup or drinking vessel, as H', which normally rests upon the drip-plateL L to keep the Ivalve closed; but when said vessel is lifted the valveautomatically opens to allow discharge of water through the spout 7.

In the application of the invention to insure perfect working thereofcare is taken to so construct the outer parts that no projections orledges are presented to support the vessel, which acts as a weight tokeep the valve closed, whereby it must of necessity be suspended by itschain when notin use. Thus in the construction first described the cap Iis rounded, so that the vessel H could not be placed thereon, and in thelatter-described construction there is no place to normally support thevessel other than the drip-plate which rests upon the lever F.

In the operation and use of the device it is obvious that the simple actof lifting the drinking vessel causes the valve to open, whereby thewater will run until the vessel is again allowed to exert its Weightagainst the pressure from the main. Thus I provide an automatic hydrantcalculated to prevent wilfnl or careless waste of water, while at thesame time an eflicient means for supply is provided.

I do not confine myself to the specific details of mechanicalconstruction as herein shown and described, as it is obvious that underthe scope of my invention I am entitled to slight structural variations.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a drinking-fountain, the combination, with a supply-pipe leadingfrom the main, a housing at the upper end thereof, having adischarge-spout, a valve having a verticalstem and a plug engagingaround said stem, of a pivoted lever extended across and resting on thevalve-stem, and a weight embodying a drinking vessel, and means wherebysaid weight is maintained in such normal relative arrangement with thesaid lever as to keep the valve closed over the outlet end of thesupply-pipe, and a casing for the parts, substantially as shown anddescribed.

2. In a hydrant, the combination, with a supply-pipe leading from themain, a housing at the upper end thereof supplied with a verticalremovable plug and a laterally-extended discharge-nozzle, a double Valvehaving a vertical-stem extended through said plug and two iiexiblesurfaces to be seated respectively against the discharge end of thesupply-pipe and the inner end of the plug, of a pivoted lever extendedacross and resting on the valve-stem, and a weight embodying a drinkingvessel so connected with the lever that its gravity normally presses thelever against the valve-stein to maintain the Valve in closed condition,and a spring to lift the lever when the Weightis lifted bya consumer,and a casing inclosing the parts, substantially as shown and described.

3. In a hydrant, the combination with a supply-pipe leading from themain, a housing at the upper end thereof supplied with a verticalremovable plug, and a laterally-extended discharge-nozzle, a doublevalve having a vertical stem extended through said plug and having twoflexible surfaces to he seated alternately against the discharge end ofthe supply-pipe and the inner end of the said plug, of a pivoted leverext-ended across and resting on the valve-stem, and a weight embodying adrinking vessel, and a chain connecting the free end of the pivoter]lever to said vessel, the weight of the drinking vessel being such that,when suspended, ils gravity maintains the valve in closed condition, anda hollow standard iuclosing the supply-pipe and housing, said standardhaving a removable cap with a slot therein through which the end of thesaid lever extends, substanlially as shown and described.

In testimony that I claim the foregoing as my invention l have signed myname, in presence of two witnesses, this 12th day of Jannary, i903.

THOMAS FRANCIS MURPHY.
